Meagrely-populated field goes to densely populated area, and impact of the explosion to surrounding is also increasingly paid close attention to by people.
Directional blasting technology utilizes the effect of explosive charge, a certain regional cubic metre of earth and stone throwing to the area specified, and
Substantially it is piled into required form.Explosion produce shock wave especially projecting to surrounding, in explosion produce dust and have
Do harm to gas and also there can be infringement to the health of people.
Chinese patent, Authorization Notice No.：The U of CN 205332934, patent name：Directional blasting device, using liquid ammonia and
The characteristic of the first rubber seal plug reduces the vibrations that explosion is produced, and its effect is only limitted to reduce the shock wave produced during explosion to week
The impact in collarette border, can not reduce flue dust and the harmful gass produced in explosion.
Utility model content
The purpose of this utility model is and a kind of directional blasting dress for proposing in order to solve shortcoming present in prior art
Put.
To achieve these goals, this utility model employs following technical scheme：
A kind of directional blasting device, including breeching cylinder, cartridge, blasting fuse and detonator, the breeching cylinder be provided with outer wall and
Inwall, the inwall is corrugated, and the cartridge is located at breeching cylinder center, the lower end of the cartridge and the nozzle of breeching cylinder
In same level, the cartridge is followed successively by from bottom to top the first detonation chamber, cushion and the second detonation chamber, and described first draws
Sealing-plug is plugged with the room mouth of shot room and the second detonation chamber, the detonator is arranged on the inside of the first detonation chamber, described to lead fire
One end of line is connected through the sealing-plug on the first detonation chamber and with detonator.
Preferably, the breeching cylinder is paper web, and the breeching cylinder is cylindrical, in the interlayer between the outer wall and inwall
Filling water stemming.
Preferably, the cartridge is made up of butyl material, and the cartridge is cylindrical.
Preferably, dry ice is filled in the cushion.
Preferably, first detonation chamber and the second detonation chamber are built with explosive.
Preferably, the ratio of the breeching cylinder and cartridge diameter is 2:1.
Beneficial effect in this utility model is：During directional blasting, the explosive segmentation blast in the device can reduce explosive
The fierce impact that disposable blast is produced；The active force that the expansion of dry ice volume heat is produced can also offset part explosion wave；
The corrugated inwall of breeching cylinder has cushioning effect to the shock wave that blast is produced；Water stemming in breeching cylinder is formed in blast
The absorbable harmful gass of water curtain and depositing dust, the directional blasting device effectively alleviate the impact of shock wave Adjacent Buildings affect and
Reduce the content of dust in air and harmful gass after explosion.
Description of the drawings
Fig. 1 be the utility model proposes a kind of directional blasting device structural representation；
Fig. 2 is breeching barrel structure schematic diagram；
In figure：1- breeching cylinders, 2- cartridges, 3- sealing-plugs, 4- blasting fuses, 5- detonators, the detonation chambers of 6- first, 7- bufferings
Layer, the detonation chambers of 8- second, 11- outer walls, 12- inwalls, 13- water stemmings.
Specific embodiment
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole
Embodiment.
With reference to Fig. 1-2, a kind of directional blasting device includes breeching cylinder 1, cartridge 2, blasting fuse 4 and detonator 5, detonator 5
Model SANKOSA, breeching cylinder 1 is provided with outer wall 11 and inwall 12, and inwall 12 is corrugated, and cartridge 2 is located in breeching cylinder 1
The heart, the lower end of cartridge 2 and the nozzle of breeching cylinder 1 in same level, cartridge 2 be followed successively by from bottom to top the first detonation chamber 6,
Sealing-plug 3 is plugged with the room mouth of the detonation chamber 8 of cushion 7 and second, the first detonation chamber 6 and the second detonation chamber 8, detonator 5 is arranged
In the inside of the first detonation chamber 6, one end of blasting fuse 4 is connected through the sealing-plug 3 on the first detonation chamber 6 and with detonator 5.
Breeching cylinder 1 is paper web, and breeching cylinder 1 is cylindrical, and water stemming 13 is filled in the interlayer between outer wall 11 and inwall 12,
Water stemming 13 forms water curtain under the impulsive force of explosion gas, can depositing dust and absorb blast in harmful gass；Cartridge 6 is in cylinder
Shape, cartridge 6 is made up of butyl material, and butyl rubber air-tightness is good, moreover it is possible to heat-resisting, ageing-resistant, chemical-resistant resistance, and has
Shock-absorbing performance；The inner filling dry ice of cushion 7；Explosive is respectively arranged with first detonation chamber 6 and the second detonation chamber 8；Breeching cylinder 1 and ammunition
